Using high molecular weight DNAs ( λ ‐and calf‐thymus (CT) DNAs), we investigated their flow characteristics under turbulence in a rotating disk geometry. By putting emphasis on the effect of CT‐DNA concentration, its turbulent drag reduction (DR) characteristics were compared with that of λ ‐DNA based on both DR efficiency and mechanical degradation under turbulence. Addition of spermidine into the turbulent flow as a condensing agent showed abrupt change of the DR efficiency of λ ‐DNA in a turbulent flow.
